Modern studies of perception and cognitive sciences distinguish between bottom-up and top-dawn cue processing. In the first one the stimuli drive the workings of visual awareness, whereas in the second one cognitive operations drive visual awareness. As to this distinction, the universal perception factors may all be considered as belonging to the bottom-up cue processing, before interpretation...

In this paper, as a first step towards constructing a selective sound segregation model for use in modeling phenomena such as the cocktail party effect, we consider a basic problem of selective sound segregation for instrument sounds using a singlechannel method (monaural processing). We propose a model concept for selective sound segregation based on auditory scene analysis and then describe i...

Our goal is to generalize the well known bottom-up, set-oriented query evaluation for deductive databases in two aspects: First, we consider arbitrary clauses as rules in the database, not only Horn clauses or clauses with stratified negation. This allows to represent disjunctive information, in the database as well as in answers to queries. We utilize NF2 relations for modelling sets of disjun...

Shift-reduce parsing has been studied extensively for diverse grammars due to the simplicity and running efficiency. However, in the field of constituency parsing, shift-reduce parsers lag behind state-of-the-art parsers. In this paper we propose a semi-supervised approach for advancing shift-reduce constituency parsing. First, we apply the uptraining approach (Petrov, S. et al. 2010. In Procee...

In recent years we have resgitered a renewed interest in event detection and temporal processing of text/discourse. TimeML (Pustejovsky et al., 2003a) has shed new lights on the notion of event and developed a new methodology for its annotation. On a parallel, works on anaphora resolution have developed a reliable methodology for the annotation and pointed out the core role of this phenomenon f...

evolved to promote and integrate virus production with VS formation. In addition to initiating signal transduc-tion in the infected cell, adhesion molecule engagement at the VS ostensibly activates the uninfected target cell. Activation would ensure expression of virus receptors by the uninfected cell and promote virus replication once the virus has entered its new target. The identity of the H...
